Application med June 7`,

To all whom it may concern:

Bei it known that I, SAMUEL L. MILLER, a citizen of ythe United States,residing at Chicago, in the countyof Cook and Statev easy positioningtherein of the respective spective binding post in apparatus and toinsure accurate proper positioniof `the apparatus, eliminatinginconveniences contingent with approved types of cabinets now onvthemarket in which it is relatively diicult to properly position thereproper alignment with the cabinet openings.

Another object of this invention is to provide a radio apparatus cabinetas speciiied which comprises a subbaseslidably supported, in suitableyguides upon the base proper of the cabinet, which subbase carries allof the instruments or apparatus and has standards rising therefrom whichcarry the various binding post, so that as the subbase is moved intoposition in the cabinet the rel-f ative binding post will be moved intodirect `alingrnent inv and through the respective openings in the backof thecabinet.

Other objects of the invention will appear in the following detaileddescription taken in connection with the accompanying drawing wherein:Fig. 1 is a vertical section through Athe cabinet showing the subbaseand the apparatus carried thereby in side elevation, and partlywithdrawn from the cabinet.

Fig. 2 is a rear elevation of the improved cabinet.

Fig. 3 is a vertical section taken on the line 3-3 of Fig. 1.

Fig. 4 is a fragmentary vertical section taken on the line H of Fig. 3.

Fig. 5 is an enlarged fragmentary section of a part of the cabinet.

'Referring more particularly to the drawings, the improve cabinetcomprises the 'A main cabinet 1 which is constructed of wood oranalogous material, and is rectangular in shape having its front side 2open. The

' bottom 3 of the cabinet 1, extends beyond the front edges of the sides4 of the cabinet, and it also projects Alaterally of the sides 4 forminga flange 5 about the front and 1922. Serial No. 566,661.

sides of the cabinet. l. The back 6 of the cabinet'is provided withvertically extending recessesor cut out portions 7 in which panels 8 ofbakelite, or analogous insulating material areseated, which are providedwith suitable openings 9 aligning with the openings 10 formed in theback 6 to permit the extension there through of the various binding post11 which are utilized for connecting the various instruments orapparatus, such as couplers, grids, amplifiers, batteries and the likein proper relation in the cabi-v net. The binding post 11 are carried byvertically supporting plates or bars 12 of insulating material which arein turn attached to the inner edge of the subbase or bottom 13. The subba'se or bottom 13 has its edges engaged in guiding slots 14 formed inthe sides 4 of the cabinet 1 and-this subbase is slidable'over the base3 to permit it to be extended as shown in Fig. 1 of the drawings 0rcompletely removed from the cabinet 1 for purposes of changing oradjustment of the various instruments or apparatus, as indicated at A,'which .are carried .by the subbase 13,. All of the'various apparatus A,or their carrying sockets are rigidly attached to the subba'se 13 andconnected to the respective binding post 11 which are also permanently.attached to the subbase 13 through the medium of the bars or plates 12.The front 15"'of the cabinet is attached to the subbase 13 and it mayhave the usual form 0f dial 16 or the like carried thereby.

A bracket 16 is carried by the subbase 13 and it has an upstanding ear17 formed thereon which is provided with a screwl threaded opening 18into which a thumb screw 19 threads. The thumb screw 19 is rotatablycarried by a sleeve 2O carried by the back 6 of the cabinet 1 and lisadapted to be threaded into the ear 17 for connecting the subbase 13 inits proper position for holding the respective apparatus carried therebyproperly within the cabinet 1.

.From the foregoing description taken in connection with theaccompanying drawings it will be apparent that an improved cabinet forradio apparatus has been provided, in-which all of the instruments 0rapparatus, being carried by the subbase may be easily changed or alteredwhen necessary and that all of the various apparatus will be properlyand accurately positioned within the cabinet with a minimum effort,

such eiort requiring only the sliding of the subbase into the cabinet,Iwhich sliding 'movement is guided by the guides 14: 'soas to permit thebinding post to extend directly to and through their respectiveopenings.

y invention vvhat 1. In Aa cabinet for. radioapparatus, a'

cabinet'having its front side open land including a base,.an apparatuscarrying subbase slidably resting upon said rst named base, anupstanding front carried by said subbase rality of openings in its rearside, upstanding plates carried at the inner edge of said subbase, andbinding posts carried by 'said plates for insertion through saidopenings. 2. In a cabinet for lradio apparatus, a

cabinet having itsvfront side open and including a base,`

an apparatus carrying subbase slidably resting upon said first namedbase, an upstanding front carried by said subbase for forming' the frontof thesaid cabinet, said cabinet provided witha plurality of openings inits rear side, upstanding plates carried at the inner edge of saidsubbase,

bindingl posts carried by said'plates for insertion through saidvopenings, and guiding means for guiding vmovement of said subbase toproperly hold and position for forming the` front ofthe said cabinet,said cabinet provided with a plusaid binding posts in alignmentrespective openings.

3. In' a Vcablnet paratus carrying subbase, said sides provided withguiding recesses receiving the edges of said subbase for guidingmovement for radio apparatus, cabinet comprislng a base and sides, anap-v wah their'.

of the subbase into the cabinet, said cabinet having its front sideopen, a panel carried4 by said subbase for forming the front side ofsaid cabinet, said cabinet comprising a backhavinga pair of strips of'insulation inlaid therein, said strips of insulation and Y bacl;provided With aligning openings, and

-vertical insulating plates carried by` saidV subbase, and binding postson said vertical. plates for insertion through' said openings,

4. In a vcabinet for radioapparatus, a

cabinetcomprising a base and sides', an ap-4f paratus carrying subbase,said sides provided with guiding recesses receiving the edges of saidsubbase for guiding movement of the subbase into the cabinet, saidcabinet having its front slde open, 'a panel carried by' said subbasefor forming-the -front-'side of said cabinet, said cabinet comprising'-a back having a pair' of strips of insulation inlaid therein, saidstrips of insulation-and back provided with aligning openings,

vertical insulating plates carried by said subbase,` and binding, postson -said vertical plates for insertion through said openings,

and means for locking said subbase in posltion withinsaid cabinet. l
